The LINE IN sockets  on the sub-woofer are con- nected to the output sockets of the pre-amplifier using Cinch leads.

The speaker's internal crossover passes the low- frequency part of the signal to the sub-woofer.

Use without control voltage:

The automatic power-on circuit is triggered by the pre- amplifier signal.

* Use with control voltage (optional):

If the pre-amplifier features a control voltage output, this control voltage is passed to the SC LINK socket  via an adaptor lead. This triggers the automatic power-on cir-cuit.

The  P 1220 R pre-amplifier supplies a control voltage at the CRTL OUT socket.

Connecting the sub-woofer to a surround decoder

The settings of the switches / , ,  and  can be

The Cinch lead carrying the SUB OUT signal from the surround decoder is connected to one of the sub- woofer's LINE IN sockets .

Since the SUB OUT signal is filtered in the decoder, the Filter switch  must be set to the 'FILTER OFF' position.

Use without control voltage:

The automatic power-on circuit is triggered by the SUB OUT signal.

* Use with control voltage (optional):

If the surround decoder features a control voltage output, this control voltage is passed to the SC LINK socket  via an adaptor lead. This triggers the automatic power-on circuit.

The  DD 1210 R and DD 1510 R surround decoders supply a control voltage at the 5.1 OUTPUT socket.
